The if function takes three arguments. The first is the comparison which will either return
true or false. The seccond is the true case which will be executed if the result of the 
comparison is true. And the last is the false case which will be executed if the result
of the comparisson is false.

(define one 1)
(define won 1)
(define two 2)

(if (= one won)
  (write "1 = 1")
  (write "1 != 1"))

(if (equal? one two)
  (write "1 = 2")
  (write "1 != 2"))
